This afternoon we used spring scales to measure how force and mass are related to motion. The students timed how long it took to pull their science book one meter using 3 Newtons of force. They then changed only one variable, either the mass or the amount of force. We found that more mass slows the motion, while applying a greater force sped up the motion. We are nearing the end of our physical science unit and beginning to synthesize everything we have learned!
